Here are the fenders from the current 1965 Raleigh Dawn Roadster project again. Previously, I shaped their bottom tips using a Dremel tool and sandpaper. This time, I will be removing rust from parts of the fenders.
If you read about the Columbia DeLuxe project
earlier (blue bike in earlier posts), you saw that I cleaned rust from
the fenders by dunking them in a large container of Oxalic Acid. The
condition of the Columbia fenders was such that an Oxalic bath was best.
The paint was badly peppered with rust, so any potential dulling was
worth removing all those little spots.
around, the paint on the fenders isn't that bad. In fact, much of the
rust is limited to certain areas and is not widely peppered the way the
blue fenders were. Moreover, the paint that remains is pretty glossy and
You don't have to dunk the entire fender
to clean the rust off. You can use a hybrid method mixing mechanical and
the inside of the fender is somewhat worse. Second, the inside is much
less visible than the outside. This means I can use an Oxalic pool.
Rather than dipping the entire fender, I prop it up until the Oxalic
bath water sits in it over the rusty areas. You can modify the position
of the fender to hit different areas of the inside well. Moreover, it
can get into places where the Dremel cannot reach. Even if it dulls the
paint a bit, that area is not really seen because it goes up against the
wheel. If you're doing a show bike, this may not be the best method.
But, if you're doing a rider restoration, this can work nicely. After a
couple of hours of checking, the rust in that area is gone and I rinse
the solution out with tap water, then rub dry. The bare areas will also
be filled later with matching paint.
So there it is:
the outside parts have ok paint that is still glossy, and the Dremel can
reach the rust. So I use that on the outside. On the inside, the paint
shine is somewhat less important and the areas are harder to reach, so I
use an Oxalic pool method. I never did a full dunk, yet I used a couple
of approaches to remove rust, depending on the needs of each area of
